What stands out in this watch:

In 1978, Seiko launched the world's first Quartz saturation diver's watch, using about 20 patent applications registered by Seiko. In 2018, Seiko is re-creating this watch and reviving the legend.
This updated model is 1000 metres water resistant.
This watch is made with a limited edition of 800 Pieces.
Rose-gold with violet tint saturation divers watch.
Fitted with titanium inner case with black hard-coating and powered by a quartz movement.
Outer case is made of Zirconia ceramic. Zirconia Ceramic is seven times harder than stainless steel and even more resistant to corrosion than titanium.
Silicone strap watch with buckle clasp.
The crown has screw-down protection to prevent it from being pulled out by any accidental operation. Greater security is achieved by positioning the screw-lock crown at the 4 o'clock position.
The deep grooves in the bezel are designed for easy operation, even when diving gloves are worn.
This watch from the Seiko collection features a black dial with luminous hands and bold circular hour markers, and the "Seiko" logo at the 12 o'clock.

More features:

Premium curved sapphire crystal glass with anti-reflective coating provides better protection from scratches in your daily life.
Rose gold plated case with a uni-directional 120-click bezel.
The black styling of this watch make for a bold piece, perfect for any occasion.
The dial features two complications, one for the day and date at the 3 o'clock position.
